KEY MESSAGES

- Unseasonably mild stretch of weather continues through Tuesday, with temperatures trending down and towards seasonal normals through the second half of the week. - Aside from a quick-hitting system bringing the chance of light rain Wednesday for some, mostly dry conditions are expected through much of the forecast period.

SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 1204 PM CST Sun Nov 8 2026

Slow-moving cold front continues to work through our area today, where it will eventually stall out near our south tonight. Overnight tonight, we will see weak ridging pass overhead. As this feature passes east through Monday AM, warm advection will increase out of the southwest. The increasing warm advection will help push this stalled boundary north through the area in the form of a warm front, resulting in widespread temperatures in the low 60s. Otherwise, we will see quite the pleasant day with a southwesterly breeze and mostly clear skies. We can expect milder temperatures Monday night into Tuesday, with most in the low-mid 40s.

LONG TERM /TUESDAY THROUGH SATURDAY/

Issued at 1204 PM CST Sun Nov 8 2026

Unseasonably mild conditions will continue Tuesday into Wednesday, as we see weak ridging and warm advection ahead of an approaching wave. Daytime temperatures in the low 60s can be expected for most on Tuesday, with some passing clouds early and light winds. Going into Wednesday, the aforementioned wave passes overhead, bringing increasing cloud cover and precipitation chances. Confidence on rainfall is low-medium, owing to uncertainty on moisture availability. Although, a look at model soundings would indicate that we might saturate enough for light showers, but it might take some time through the day for it. Thus, current PoPs might be a little ambitious on the rainfall chances earlier in the day. Compared to the last forecast package, we have seen an increase in PoPs with the NBM, with best chances now generally along/north of Interstate 80. While the chances may have increased (30-50%), we are expecting light rainfall with low accumulation. WPC continues to favor <0.10" for those seeing light rain. Otherwise, a mostly cloud day can be expected with temperatures in the mid-upper 50s.

This system will be quick to move out, with notable cold advection kicking in on the back end. Not only will dry air work back into the area, but we will also see much cooler air work in. Granted, we will remain near seasonal norms in the low-mid 40s, but these are cooler daytime temps than we have seen over the last few weeks. Breezy gradient winds will also kick in on the back-end of the system Thursday, resulting in a chilly breeze. High pressure will then settle into the region late this week and into the weekend, bringing a period of cooler and quiet weather.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1109 AM CST Sun Nov 8 2026

VFR conditions will prevail through the TAF period, with a weak cold front continuing to move out by 00z. Behind the front, we are seeing winds of 10-15 KTs out of the northwest. By 00z, we will see winds go light and out of the northwest, eventually becoming light and variable. Otherwise, no sig wx is expected at this time.
